Objective:To explore the clinical features, diagnosis and treatment of febrile infection-related epilepsy syndrome (FIRES).Methods:The clinical data of 2 cases of FIRES admitted to Changde First People′s Hospital from 2020 to 2022 were retrospectively analyzed, and the clinical characteristics, diagnosis and treatment methods and prognosis of the disease were discussed in combination with relevant literature.Results:Two children with FIRES were all acute onset, with fever as the first symptom, and status epilepticus appeared 3 to 5 days later. The efficacy of various antiepileptic drugs was poor. After ketogenic diet treatment, one child recovered well, and another child still had frequent convulsions under ventilator assisted breathing on the 27th day of admission. His family signed to give up the treatment. At the same time, compared with the domestic and foreign literature, the clinical characteristics of the two children are basically the same as those of the reported cases.Conclusions:FIRES is common in healthy children in the past. After seizures, it rapidly progresses to status epilepticus. MRI of the head and cerebrospinal fluid can have no characteristic changes. The effect of routine antiepileptic drugs is not good. Ketogenic diet can improve the condition of children, but the overall prognosis is not good.
2.Biological function and mechanism of CMTM family
Chinese Journal of Cancer Biotherapy 2019;26(4):463-467
CMTM家族作为一个新的基因家族,在免疫、生殖等系统以及多种肿瘤的发病机制中起到重要作用。CMTM家族中, CMTM1可影响细胞增殖,导致肿瘤发生;与非小细胞肺癌(NSCLC)患者的化疗耐药和预后有关。CMTM2通过AP-1、CREB通 路一定程度上影响HIV-1转录,同时在男性生殖系统中起重要作用。CMTM3等位基因失活或甲基化使其丧失对细胞增殖的负 性调控能力,是胃癌独立的预后指标。CMTM4调控细胞周期影响肿瘤细胞增殖,通过对PD-L1的协同保护参与免疫逃逸。 CMTM5在许多肿瘤中沉默表达,参与肿瘤发生发展相关的信号通路。CMTM6协同PD-L1参与免疫逃逸,是潜在的免疫治疗靶 点。CMTM7在NSCLC中通过Rab5控制EGFR-AKT信号影响肿瘤发展,且与胃癌发展相关。CMTM8通过MARVEL区域影响 EGFR和相关信号通路,调控细胞增殖、分化和凋亡等。上述重要发现,为研究肿瘤的发生发展及肿瘤基因治疗提供了新思路。

Chinese Journal of Cancer Biotherapy 2019;26(5):544-549
Objective: To evaluate the expression of CKLF-like MARVEL transmembrane domain containing member 6 (CMTM6) in lung adenocarcinoma tissues, and to explore its correlation with the clinicopathologic features and prognosis of patients. Methods: Eighty-six pairs of cancer tissues and para-cancer tissues from patients that pathologically confirmed with lung adenocarcinoma were collected during September 2004 and June 2009 at the Third Affiliated Hospital of Soochow University. The expression levels of CMTM6 in above mentioned tissues were detected by immunohistochemistry. Serum of 52 patients with confirmed lung adenocarcinoma was collected before and after surgery, and serum of 32 healthy subjects was also collected. The levels of CMTM6 and PD-L1 in peripheral blood before and after surgery were measured and analyzed by ELISA. Chi-square test was used to analyze the relationship between CMTM6 expression and clinicopathological features; Kaplan-Meier method and Log-Rank test were used to analyze the survival data of patients. Results: CMTM6 was widely expressed in lung adenocarcinoma tissues; 30% of the tumor tissues showed an up-regulation as compared with para-cancer tissues, and 70% showed no difference. CMTM6 expression was associated with clinical stage and distant metastasis (all P<0.05), but not significantly associated with age, gender, tumor size, and T stage (P>0.05). Kaplan-Meier survival analysis showed the survival rate of patients with high CMTM6 expression was significantly lower than those with stable expression (P=0.014), and among patients at stage Ⅲ, the survival rate of patients with high CMTM6 expression was significantly lower than those with stable CMTM6 expression (P=0.001). Cox regression model analysis of multiple factors showed CMTM6 expression was an independent risk factor for the prognosis of patients with lung adenocarcinoma. CMTM6 expression in pre-surgery serum, post-surgery serum and healthy donors’serum showed statistically significant differences (P<0.05), which was significantly correlated with tumor size and age of the patients. Spearman correlation analysis showed a significant correlation between serum CMTM6 and PD-L1 expression level (r=0.623, P<0.01). Conclusion: CMTM6 is an independent risk factor for the prognosis of lung adenocarcinoma patients. It plays an important role in the occurrence and development of lung adenocarcinoma and it is a potential tumor suppressor gene.

Objective To study the in vitro anti-tumor activity of dendritic cells (DCs) loading with antigen produced by radiofrequency ablation of tumor lysate in situ combined with cytokine-induced killer cells (CIK).Methods CIK ceils derived from BALB/C mouse spleen and DCs derived from bone marrow were prepared,and experimental model of murine colon carcinoma were established for radiofrequency ablation.The supernatant of tumor tissue in situ lysis after repeated freezing and thawing were tested by lowry protein quantitative statutory,amounting to a final concentration of 5 μg/ml,then load to the first 5 days of culture DCs (Ag-DC),2 days later,co-cultured with CIK cells after the first seven days of culture 48 h (Ag-DC-CIK).Flow cytometry was used to analyze costimulatory molecules on the surface of the cells,and CCK-8 assay to detect in vitro cytotoxic activity.Results The DCs loading with antigen resulted in an increase in the proportion of CD86 + CD11 c +,MHC Ⅱ + CD11 c + and MHC Ⅱ + CD80 + cells.The main effector cells of CIK cells were CD3 + NK1.1 + cells.The percentage of CD3 + NK1.1 + cells was 1.45% on the first day of the culture ; while when they had been cultured for 7 days,the percentage CD3 + NK1.1 + significantly increased to 36.9%.The cytotoxicity of Ag-DC-CIK cells toward C26 cells was much more efficient than that of DC-CIK,CIK cells.The cytotoxic activity of the former was significantly lower than the latter and the same target ratio.When the ratios of effector cells to target cells were 5 ∶ 1,the cytotoxic activity of Ag-DC-CIK cells against C26 cells was (74.9 ± 3.5) %,; while the DC-CIK was (71.2 ± 2.1) % and the CIK cells was (68.7 ± 2.9) %.The difference was statistically significant(F =7.007,P =0.007).When the ratios of effector cells to target cells were 10 ∶ 1,the cytotoxic activity of Ag-DC-CIK cells against C26 cells was (82.3 ± 4.5) %,while the DC-CIK cells was (77.1 ± 5.1) %,and the CIK cells was (72.7 ± 2.8) %.The difference was statistically significant (F =7.727,P =0.005).When the ratios of effector cells to target cells were 20 ∶ 1,the cytotoxic activity of Ag-DC-CIK cells against C26 cells was (83.2 ± 1.9) %,while the DC-CIK cells was (77.2 ± 4.2) %,and the CIK cells was (73.0 ± 2.6) %.The difference was statistically significant (F =16.594,P =0.000).Conclusion DCs loading with antigen produced by radiofrequency ablation of tumor in situ pyrolysis products can improve in vitro cytotoxic activity combined with CIK cells,which can provide a new comprehensive cancer treatment strategy.
